My husband has Acute Lymphocytic Leukemia and has a PICC line. The hospital’s transplant units were using Port Protectors and they sent us home with some. This has been the first PICC line out of FOUR in which he has not gotten an infection, and he’s had this line in for 3 months! We are so convinced that your product has kept his line infection-free, that we will purchase them outright.
